AUGER-TWISTING MAGHINE.

SPECIFICATION forming part of Letters Patent No. 777,576, dated December 13, 1904:.

Application filed October 26, 1903. Serial No. 178,526. (No model.)

To all whom it nuty concern.-

Be it known that I, IsAAo WANTLING, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Auger-Twisting Machines; andI do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to improvements in machines for twisting auger-bits for coal or rock drilling machinery, and has for its object to uniformly and automaticallytwist such augers.

A further object of the invention is a reciprocating twister-head and means for governing the rotation of such twister at the same time as it reeiprocates the same.

A further object of the invention is a carriage governed in its movements by threadbars which are suitably actuated, a rotating twister movable with such carriage, means for returning the carriage to its starting-point, and a water-supply for cooling the augers as they are twisted.

A further object of the invention is an automatic shiftable carriage and interchangeable thread-bars to govern the movement of the carriage and the pitch of the spirals of the auger, nuts of the carriage adapted to engage the thread-bars, and means for causing the nuts to grip or be released from such' thread-bars.

Further objects and aims of the invention will be more clearly pointed out in the following specification and drawings, forming a part thereof, in which Figure 1 is a plan View of the machine. Fig. 2 is an end view of the front end thereof. Fig. 3 is a cross-section through the machine-bed, showing an elevation of the carriage, twisterhead, and nuts adapted to engage the threadbars. Fig. 4 shows one form of feeding-rolls.

Fig. 5 shows one form of anger twisted on the machine.

In the drawings the bed-frame of the machine consists of the parallel longitudinal frame parts 1, connected at the opposite ends by the cross-fran1es 2 by bolting or otherwise standards for supporting such bed-frame.

4 denotes thread-bars extending longitudinally of the machine-bed in proximity to the frame parts 1, as shown, with their opposite ends journaled in the boxings 5 and 6, carried by the cross-frames 2. It is adapted to employ varying forms of thread-bars or bars whose threads are cut more or less to the inch for purposes soon to become apparent.

7 7 indicate parallel cross-franiies, together forming a carriage through which the thread bars extend, and by the use of frames 1, sub stantially I-beams or channel-bars, the ends of the frames 7 move in such channels and are provided with shoes 8, which move along the bottom of such channels and serve to steady the carriage during its work.

Through the center of the carriage-fra1ne parts 7 is carried a short shaft or spindle 9, its forward end provided with the slot 10, and on said shaft and between the frame parts 7 is carried the large spur-wheel 10, and such wheel meshes with duplicate pinions 11 upon opposite sides of the machine, which are feathered on the thread-lmrs a, the latter grooved, as at 12, for this purpose.

13 denotes nuts formed of two half-sections pivoted together at 14 to the frame part '7 and adapted to open and close upon the threads of the bars 4. To accomplish the opening and closing of the nuts on the threadbars, I have provided a lever 15, fulcrumed on the twister-shaft 9. To the body of the lever and having pivotal connection, as at 16 and 17, are the oppositely-operating rods or links li and 19, whose opposite ends are connected at 20 and 21 with the ears 22 and 23 of the opposite sections of the nuts 13. On the shaft 9 is carried a sleeve 24, formed with a groove in which carried and has bearing the lever 15. (See Figs. 1 and 3.) To lock the position of the levenwhen in the position shown in the figures, which causes the nuts to engage the thread-bars at, a pawl 25 is provided, pivoted to the body of the lever, as at 26, and the same engages a tooth or depression. 27 in the upper edge of one of the bars 7 of the carriage and a releasing-finger 28, provided for raising the pawl 25 when it is desired to shift the lever 15, which results in throwing the arms 18 and 19 in opposite di rections and separate the sections of the nuts.

Power is imparted to one of the bars at through a pulley 29, connected with suitable power, which when the nuts 13 are engaging the bars will shift the carriage from the forward to the rear end of the bed and through the pinions 11 and gear 1O rotate the twistershaft 9. \Vhen the carriage reaches a desirable point in its movement, the lever is thrown, releasing the nuts, and by means of the shaft 30, journaled in bearings in the standards 3, around which chains 31 are car ried, connected to the carriage, as at 32, the carriage is drawn to the forward end of the machine and a crank 33 employed to actuate the shaft 30. This means of reversing the carriage is simple, convenient, and quick; but it is understood that any suitable mechanical means may be employed without affecting or changing to any great extent the operation of the device.

Guiding and forming rollers 34 are provided, journaled in removable bearings 35, arranged somewhat in the manner shown in Figs. 2 and 4, between which a heated bar is passed as the auger is formed. The rollers 34 are preferable when twisting an auger having a square edge, (see Fig. 1,) and the rollers shown in Fig. 4 are preferable when twisting an auger having a feathered edge, (see Fig. 5;) but in this 1 do not wish to be limited.

In making an anger a red-hot bar 36 is passed from a furnace through the rollers 34 and the end of said bar slipped into the slot 10 of the twister-shaft 9 and retained therein by the bolt or pin 37 passing through the sleeve 24. It, will now be seen as the carriage moves away from the feeding and guiding rollers 34 the twister-shaft rotating will uniformly twist the bar 36 as it emerges from between the rollers 34, (see Fig. 1,) and to cool the metal as the twist is made water is sprayed onto the twist as it is formed from a pipe 38,-connected with a suitable supply and the supply governed by a valve 39. The pipe 38 has a pivotal connection with the main supply to permit of the same being swung out of position when not in use.

It is understood that different twists of the augers are made by changing the thread-bars which actuate the gears, which in turn actuate the twister-shaft. The manner of securing the bars 36 in the shaft 9 maybe modified and other and various changes made throughout the device without affecting the principle and operation of the invention herein.
